period? or pregnant?

Brittany

I normally don't post to forums about what my body does or doesn't do. I have an irregular period and always have. I started tracking it so that I could roughly know when I should get it. last month my period was 10 days late but I took a test and it was negative. This month my period is 4 days early. it's brown and bright red. While my fiance and I aren't planning we're not really preventing either... I want another baby so i'm too nervous to take a test and it be negative again. help! any thoughts or words of wisdom??
